Laser imaging SF6 leakage positioning device

Abstract

The invention provides a laser imaging SF6 leakage positioning device, including a power unit, a laser which is connected with the power unit and is supplied by the power unit, first germanium lens which is arranged before the laser to make the laser pass through, an infrared imaging device which is connected with the power unit and is supplied by the power unit, second germanium lens which is arranged on the front end of the infrared imaging device and makes reflected or backscattered laser pass through the second germanium lens and go into the infrared imaging device, a main processing unit which is connected with the output part of the infrared imaging device and judges the leakage position of SF6 according to the electric image signals output by the output part of the infrared imaging device and a display which is connected with the output part of the main processing unit to display output results. The device can make SF6 leakage air which can not be observed under normal condition visible and clear in standard video display. Detection personnel can fast make sure SF6 sir leakage source through an intuitive image in the display.

Description

technical field [0001] The invention relates to a laser imaging SF6 leakage location device in the field of electric power transmission and transformation; especially for indoor GIS (high-voltage combined electrical switch) or outdoor GCB (SF6 circuit breaker and its A laser imaging SF6 leak location device for gas location leak detection and diagnosis of supporting equipment). Background technique [0002] As a necessary part of the power transmission and distribution process, switchgear is widely used in the power production and management of functional departments such as power plants and power supply bureaus in the power system. In practical applications, whether it is a domestic or foreign switch manufacturer, due to factors such as the production process, sealing process and site environment of the product, there are more or less different degrees of SF6 gas leakage. The specific leakage parts include compartments, Insulators, O-rings, switch insulating rods, secondar...

AI Technical Summary

Problems solved by technology

[0003] Heavy quality, large volume, cumbersome to use, cannot meet the needs of users for flexible and convenient use

[0004] Unable to pinpoint leak focus

[0005] Unable to clearly reflect which is SF6 gas

[0006] It cannot be stored in picture format, which is not convenient for the transfer, query and filing of U disk

[0007] The infrared imaging device cannot be disassembled and can be used alone
